Quizplus · Accepted Answer

In a hierarchical DBMS, parent records can have multiple child records, but child records can have only one parent record. This is because the data is organized in a tree-like structure, where each parent has many children, but each child has only one parent. While a hierarchical DBMS may work well with certain types of data, such as highly structured data with a clear hierarchy, it may not be as suitable for more complex data structures. Therefore, statement C is not necessarily true. Statement A is incorrect as child records cannot have more than one parent record.
